runtime: use frame pointer unwinding for block and mutex profilers Use frame pointer unwinding, where supported, to collect call stacks for the block, and mutex profilers. This method of collecting call stacks is typically an order of magnitude faster than callers/tracebackPCs. The marginal benefit for these profile types is likely small compared to using frame pointer unwinding for the execution tracer. However, the block profiler can have noticeable overhead unless the sampling rate is very high. Additionally, using frame pointer unwinding in more places helps ensure more testing/support, which benefits systems like the execution tracer which rely on frame pointer unwinding to be practical to use.
